Yeah dito.
And now I see Mr. KuleGamr profusely apologising in the Free For All forum, so I must have missed out on some serious fun.

I hope you guys haven't permanently deleted that thread...

I believe it got deleted... I am looking into the matter and will keep you informed.

Part of the fun of forums is having barneys with people you don't know, or reading other people having them.

I do hope it wasn't deleted permanently.

It appears it was permenently deleted by a moderator who shall remain nameless.

He has been ticked off, and I assure all, it wont happen again.

Sorry guys.

I want to make button that can be hide or shown depending the value of the textbox inside my form!

If the text box contain no value, then display the button else, hide it!

anyone can help me

Monie · #9 (**permalink**) Aug 26th, 2004, 03:02

this javascript will be put inside the updata page, where the user can update their information.

benbacardi · #10 (**permalink**) Aug 26th, 2004, 06:42

add an ID to your text box and your button, then add this code:

Code: Select all

textboxvalue = document.getElementByID('text1').value;

if (textboxvalue == "") {
document.getElementById('button1').disabled = false;
}
else {
document.getElementById('button1').disabled = true;
}

Rob · #11 (**permalink**) Aug 26th, 2004, 09:57

I should point out that the above code, although correct, would need to be contained inside a function. The function would need to be called by the textbox's onchange event.

Post back here if you have problems achieving this modification.

Monie · #12 (**permalink**) Aug 27th, 2004, 04:19

well thanx benbacardi, and thanx rob for reminding me

Monie · #13 (**permalink**) Aug 28th, 2004, 03:17

hai rob and benbacardi...
i have a hard day trying to run the code. actually i dont know how to use it.
can you show me how to do it,please

can you show me the <HEAD> script as well

this is the code page that will contain two textbox (subject,section)
and two button(update record,delete)--delete will empty the textbox value =''
this is my update page(dbUpdate.asp)
disable the two button if both the textbox contain value inside it!

Code: Select all

<tr>
	    <td width="31%" height="28" align="center"> 
               <p align="right"><font face="Verdana" size="2">
	       Subject :</font> 
           </td>
        
  	   <td width="69%" height="28" align="center"> 
               <div align="left"><font face="Verdana" size="2">
               <input id="subject" name="subject" value="<%=(Recordset1.Fields.Item("subject").Value)%>" size="32" style="float: left">               </font></div>
           </td>
        </tr>
        
	<tr> 
            <td width="39%" height="28" align="center"> 
               <p align="right"><font face="Verdana" size="2">
	       Section :</font> 
            </td>
            <td width="61%" height="28" align="center"> 
               <div align="left"><font face="Verdana" size="2"> 
               <input id="section" name="section" value="<%=(Recordset1.Fields.Item("section").Value)%>" size="32" style="float: left">
               </font></div>
            </td>
        </tr>
        
        <tr> 
            <td width="100%" height="28" align="center" colspan="2"> 
               <font face="Verdana, Arial, Helvetica, sans-serif" size="2">*</font>
            </td>
        </tr>
        
        <tr> 
            <td width="100%" height="28" align="center" colspan="2"> 
               <font face="Verdana, Arial, Helvetica, sans-serif" size="2"> 
               <input type="submit" value="Update Record" name="submit">
               
               <input type="button" value="Delete Record" name="delete" a href="#" onClick="document.getElementById('subject').value =''; document.getElementById('section').value = '';">
               </font>
               
            </td>
        </tr>

When the textbox "Subject" and "Section" are empty, contain no value, then display the "Update Record" button!
Else if the textbox "Subject" and "Section" contain a value/ data, then disable the "Update Record" and "Delete" button
and display a "BACK" button to go back to previous page!
can you show me step by step

benbacardi · #14 (**permalink**) Aug 28th, 2004, 10:07

ok.... first you need to add an id to the two buttons:

Code: Select all

<input id="update" type="submit" value="Update Record" name="submit">
<input id="delete" type="button" value="Delete Record" name="delete" a href="#" onClick="document.getElementById('subject').value =''; document.getElementById('section').value = '';">

next, you need to write the function that disables the button. This will need to be in the head of the page, in <script></script> tags:

Code: Select all

<script language="javascript" type="text/javascript">
<!--

function check() {

if ((document.getElementById("subject").value = "") && (document.getElementById("section").value = "")) {
document.getElementById("update").disabled = false;
document.getElementById("delete").disabled = true;
}
else {
document.getElementById("update").disabled = true;
document.getElementById("delete").disabled = false;
}
}

//-->
</script>

next, you need to add an onchange event to the two text boxes, that calls the function:

Code: Select all

<input onchange="check()" id="subject" name="subject" value="<%=(Recordset1.Fields.Item("subject").Value)%>" size="32" style="float: left">
<input onchange="check()" id="section" name="section" value="<%=(Recordset1.Fields.Item("section").Value)%>" size="32" style="float: left">

of course, if you want it to be checked when the page loads, you also need to add the function call in the onload event of the body:

Code: Select all

<body onload="check()">

hope this helps....

i wasn't too sure about what you meant by the back button....

Rob · #15 (**permalink**) Aug 29th, 2004, 08:51

Monie.... please can you use forum code when posting script. You need to surround any pasted code with these tags:
[*code] script here [*/code] (remove asterisks)

Monie · #16 (**permalink**) Aug 30th, 2004, 03:32

Code: Select all

testing....
ok rob,
thanx for telling me that:)
and thanx a lot for benbacardi! Your code really helps me alot!

Monie · #17 (**permalink**) Aug 30th, 2004, 03:35

hey guys....
i am wondering, if I can disable a button, can i disable a text as well?
what changes i must do in the code if i want to disable a text?

Webforumz Staff · #18 (**permalink**) Aug 30th, 2004, 06:21

You don't need to change anything other than use the id for the text field in the disabling code.

Monie · #19 (**permalink**) Aug 31st, 2004, 06:22

hey benbacardi, i am having a big problem here!
could you help me please

the code that you gave me is to check if the "subject" and "section" field contain a value!

if it contain a value, disable the book button, and if it does not contain any value enable all the button.i have done that successfully...thanx to you

i have modify the code to check a field called "type",
if the field contain value equal to "FIXED" and "BOOKED", disable the book button! this field is entered by the admin!

but if the field contain the value "AVAILABLE"(set by admin), enable the book botton!
can you help me! i have been trying to modify the code but i dont know how to do
the checking part

this is the unfinished code that i have done...

Code: Select all

<script language="javascript" type="text/javascript">
<!--
function check() {

if (document.getElementById("type").value ="<%=(Recordset1.Fields.Item("type").Value)%>")
{
document.getElementById("book").disabled = true;
document.getElementById("back").disabled = false;
document.getElementById("close").disabled = false;

else if field "type" contain "AVAILABLE"---> enable all button

please help me

benbacardi · #20 (**permalink**) Aug 31st, 2004, 06:38

you need another if statement:

Code: Select all

if (document.getElementById('type').value == "FIXED" || document.getElementById('type').value = "BOOKED") {
document.getElementById('book').disabled = true;
}
else if (document.getElementById('type').value == "AVAILABLE") {
document.getElementById('book').disabeld = false;
}
